Kylie Minogue has rewritten the lyrics to Can't Get You Out Of My Head for Cardiff University.
The new version of the number one single will help promote a student helpline at the University.
A spokesman for Kylie's record company said she had decided to rewrite the lyrics "because she felt it was a very worthwhile cause".
Daniel Weaver, the helpline's co-ordinator, told ICWales: "It's good to know that even though she's an international pop star, Kylie's still interested in ordinary people".
"We sent an information pack and a blank minidisc to Kylie's hotel when she stayed in Cardiff to play the International Arena".
"We didn't hear anything back for months, so we thought nothing more of it.
"But then we got the minidisc back through the post with Kylie's jingle on it."
The reworked version is due to be played on the University's student radio station this week.
